Crop irrigation system combined with computer vision and multi-sensor

Abstract

The invention relates to the fields of image processing technology, the sensor technology and the water-saving irrigation, disclosing a crop irrigation system combined with computer vision and multi-sensor, wherein the technology adopted by the invention is non-destructive crop water-lacking detection combined with computer vision and multi-sensor; the system comprises the steps of obtaining and dividing a crop image, and extracting characteristic parameters; computing the characteristic parameters according to a growth data model; and then combining sensor data of a soil water potential sensor, a temperature and humidity sensor and the like, finally, finishing judgment by a genetic neural network, and controlling a single chip to drive an electromagnetic valve according to a judgment result to finish crop irrigation. The system can obtain water requirement information of crops immediately, achieve accurate irrigation immediately, and improve the utilization rate of water resource. The system has good practicability and can be applied to crop plantation areas such as a greenhouse, a farmland, a nursery garden and the like.

Description

technical field [0001] The invention relates to the field of computer vision and processing technology and sensor technology, in particular to a water-saving irrigation method based on computer vision and sensors to detect crop shape, color change and environmental parameter change and make judgment and irrigation. Background technique [0002] With the development of science and technology, agricultural production is also rapidly changing the traditional farming mode, modern science and industrial technology has gradually penetrated into agricultural production, agricultural technology is gradually developing in the direction of scientific and informationalization, modern facility agriculture Emerged as the times require, and become one of the most dynamic industries in the world today. [0003] In foreign countries, the development of water-saving irrigation control system started earlier, with a high degree of automation, and a relatively complete irrigation control syste...

Problems solved by technology

However, LVDT is mainly used in industrial metrology in the field of machinery manufacturing. Although the measurement resolution and accuracy can meet the requirements, due to the rigidity of the contact point, it will affect the growth of crops, and it cannot well meet the actual requirements for crop measurement.

Some scholars also use sensors or micrometers to measure the fruits or leaves of crops, but these methods all require contact operations with the fruits or leaves of crops, and measure the slight changes in plant organs through sensors or mechanical devices to obtain water demand information to control Irrigation systems, these methods require on-site operations, are time-consuming and laborious, and because they are contact measurements, they also have a certain impact on the growth of crops

At present, some foreign scholars are also engaged in the use of short-range infrared remote sensing images to detect the water demand of crops. This technology is very expensive and has not yet reached the level of practical application.
